It measurement refers only to the order in which the events occured.

• Relative Age

• Geologic Time

• Absolute Dating

• Plate tectonics

All geological processes known today also occurred in the past, operating slowly throughout the ages.

• Relative Age

• Laws of stratigraphy

• Uniformitarianism

• Correlation

Also known as the principle of lateral continuity

• Principle of Inclusion and component

• Principle of Superposition

• Principle of crosscutting

• Principle of Faunal Succession

It is an originally deposited horizontal layer that has been folded or tilted, weathered, and eroded

• Nonconformity

• Paraconfirmity

• Disconformity

• Angular Unconformity

Geologists gather geological evidence from many localities and match rocks of the same age from different localities in a process called

• Laws of stratigraphy

• Unconformities

• Correlation

• Fossils

This principle is based on the assumptions of materials appearing in pre-existing rock layers, evident through igneous dikes forming in sedimentary beds.

• Principle of Superposition

• Principle of Faunal Succession

• Principle of Crosscutting Relationship

• Principle of horizontality

An inclusion is any foreign material found in another material

• Time Correlation

• Physical Correlation

• Principle of crosscutting relationships

Refers to continuity of a rock unit such as the sandstone

• Paraconformity

It is useful in determining the relative ages of rocks
